With NOS 5.0, Brocade VCS fabrics now provide support for network programmability using a RESTful API. In this post, I demonstrate how the API can be used to manage VXLAN overlay-gateway functionality in the VDX.

Live migration in the cloud can be useful at times as it can minimize downtime during maintenence and move instances from overloaded compute nodes. A little while back I setup a devstack cluster with a shared NFS filesystem to perform live migration of OpenStack instances from one compute node to another using KVM hypervisors.

Devstack is a scripted installation of OpenStack that can be used for development or demo purposes. This writeup covers a simple two node devstack installation using the Brocade VCS plugin for OpenStack networking (aka Neutron).

This short writup describes how to setup Red Hat’s OpenStack RDO Havana release with the Brocade VCS plugin for Neutron networking.
